The ventilation system in the house includes equipment and channels through which air is exchanged. With a properly built ventilation system, high-quality air ventilation is ensured. However, even its proper operation requires regular inspection. Value...

To calculate the rate of air exchange in residential premises, special tables are used. If the room is idle, then the indicators are reduced by 0.2-1 hours.

The calculation of the air velocity in the duct is carried out according to the cross section, tables, formulas and calculators. A system that does not comply with SNiP standards may not be allowed to operate.

Aerodynamic testing of ventilation systems is an important process, without which no building can be commissioned. All types of structures are tested.

Inspection, repair and soundproofing of ventilation systems in the apartment is carried out when problems arise. The main markers are noise, stagnation, dampness, mold and fogging.

Installation and restoration of ventilation ducts is a complex of professional works. As a result of which, the ventilation system will be established.

Disinfection and cleaning of ventilation ducts should be carried out regularly. In the absence of maintenance, dampness, signs of mold, fogging of the windows appear.

The rate of air exchange for industrial premises is in the range from 1 to 10 units. To determine the use of industry documents, SNiPs, standards.

In order for ventilation to work properly, it is necessary to calculate the area of ​​air ducts and fittings. They mainly affect system performance.

The calculation of the air exchange rate is based on the norm indicator, based on the type and purpose of the building. According to the calculation data table, it is found by the formula: L = Vpom * Kр (m3 / h).

The calculation of supply and exhaust ventilation is determined in cubic meters per hour. First of all, it is determined what height and area of ​​the room.
